Cards this CPU would hold back
RTX 5090 (17% CPU bottleneck at 1440p). Buy one of these only if you game at 4K or plan a CPU upgrade soon.
Cards that would waste this CPU
GTX 1650, RTX 3050, GTX 1660 Super leave more than 40% of the Core i7-13700K unused at 1440p — fine for esports titles at high refresh, wasteful otherwise.
